Installing Raspi-LTSP

Now you have an Ubuntu 14.04 server setup, it is time to actually install Raspi-LTSP. Raspi-LTSP is run through a terminal.
This allows you use it locally or even run the software over SSH!
Lets get started!

Once the machine reboots, login with your credentials you set up
earlier.

Select the search button in the top left corner.

Search for and select “Terminal”. You can also just hit Ctrl + Alt +
T.

You will then be presented with a terminal. Raspi-LTSP runs inside a
terminal window. You may find it useful to resize the terminal
window to make it larger or put it in full screen.

Enter wget --content-disposition http://pi-ltsp.net/downloadalpha
and hit enter. This downloads the RaspberryPi-LTSP script. The main script is called Pi_ltsp.

Once that completes, enter sudo bash Pi_ltsp which will launch
Raspi-LTSP. A desktop icon will be created when the software installs but
you can always use this command to manually launch Raspi-LTSP.

Enter your password as the application must be run as administrator
(nothing will look like it is being entered, this is a Linux security feature so don't worry, it is being entered).

Raspi-LTSP will detect its installation location is wrong. Don't worry,
it will fix it. Select ok.

The install will take roughly 1-2 hours depending on processor speed
and internet speed. Select ok and it will start the installation.
You can now leave it to work.

Around 1-2 hours later, the extra software dialog will be displayed.
Here you can select any additional software you with to install.
Libreoffice can be useful for a classroom; it is a free full office
suit, similar to Microsoft Office. You can also install a custom
package from the software repositories if you know its full name.
Once you have finished, select cancel (or finished) to move on.

Select yes when asked if you are finished installing software.

The operating system will now be compressed. After every change made
to the operating system, it must be recompressed which takes roughly
5 minutes normally. Select ok.

You must decide if you need students to have Sudo access on
the Raspberry Pi. If you intend to work with the GPIO pins on the
Raspberry Pi they will need it. You can really easily later enable
or disable Sudo use in the Manage-Users submenu in the main software
options. If in doubt, is recommended to enable it by selecting yes.

If using 2 network interface cards then check the IP address is
correct. If you are only using 1 (most people), then the default
will likely be correct. Select yes.

Raspi-LTSP installation is now complete. The server has generated an
SD card image which is located in /home/YourUser/piboot.
You need to copy these files onto a blank formatted SD card and
connect the Raspberry Pi to the network.

You are recommended to check the Backup section of this manual on
setting up an automatic backup of your students work to an external
hard drive in case of hard drive failure.
